Higher urbanization rate, the non-economic exploitation of land, and the unusual growth of urban spaces have significantly contributed to the accelerating pace of land and housing rent, with unsystematic controls making land and urban housing rent difficult, if not impossible. The present study aimed to revisit the concept of “Effectiveness of Theories of Controlling Land and Urban Housing Rent” using me-ta-analysis and systematic review methods. In this connection, articles in scientific databases were searched to investigate the theories of “Land and Housing Rent” us-ing meta-analysis and systematic review methods based on the four-stage model of PRISMA in nine conceptual dimensions. Initially, 300 articles from 2000 to 2022 were identified. Out of this, 149 final articles were selected to be included in the me-ta-analysis by data description in the CMA software, after being incorporated into a specialized protocol. Findings revealed that the combined average effect sizes (ES) of the fixed-effect model and the random-effect model were 0.243 and 0.233, re-spectively, both being statistically significant. The significance of two Cochran (Q-Test) and Squared (I2) indexes with a high heterogeneity showed the effectiveness of the nine variable-based interventions on reducing land and housing rent. According-ly, the selection of the random model as a meta-analysis model was confirmed. Test results, including high heterogeneity rates, high data accuracy, larger “Classic Fail-Safe N index” statistic, as well as the significant contribution of the nine variables to the interventions aimed at affecting land and housing rent were confirmed to be suf-ficiently valid and reliable and were regarded as comprehensive strategies. Finally, it was found that publication bias did not influence the results.

Housing is the smallest element of housing, the most important urban land use and one of the major indicators of a country's development assessment. On the other hand, demographic changes due to natural growth and migration increase the need for housing and lead to the physical expansion of cities; in principle, the lack of proper land policy in a country or a policy incompatible with economic, cultural and political conditions. It will lead to numerous problems in the field of economics. This has prompted national and local governments to develop policies to control the physical disruption of cities. The purpose of the present study is to determine the impact of these policies on the physical development of District 15 of Tehran Municipality. In this study, which is cognitive in terms of purpose and in terms of post-event nature, a qualitative approach was used by descriptive-analytical method. The field study was conducted through a survey method based on interview and questionnaire techniques. The statistical population is comprised of urban elites, professors and experts. Data analysis was done by SPSS software (Friedman test) and GIS software was used for data analysis. The results showed that demand-driven policies were more effective than supply-based policies among the effective policies on the development of Tehran's 15th district. Of all the indicators, direct government involvement in the land market (transfers in the urban land sector) has played the most role.

The provision of land-use planning in the rural settlements is considered a prerequisite of optimal living conditions. To ensure this impact, it is of utmost importance to impose regulatory provisions on land-use changes. One of the most important provisions is the rural guide plans for the control and prediction of future land allocation. However, factors composed of legal, economics, natural and social components have initiated massive changes in land-use contrary the resolutions of the rural guide plans. Notwithstanding the fact that most of these land use changes were caused by human factors, the lack of logical planning frameworks for land allocation, negligence of sustainable development considerations, absence of integrated management, and the disregard for the environmental impacts of relevant activities all play a part in the outcome.
With regard to sensitivity of the issue, this research tries to clarify which of the factors is more responsible for land-use changes in Taft County.. The current study is based on the findings of an applied research, which draws on a combination of qualitative and quantitave methods. The descriptive data were acquired from field observations in the rural setting, as well as in depth study of the available documents in physical or virtual archives. The field data were gathered through interviews with the rural residents in addition to first hand observation of the impacts of land-use changes on different dimensions of the rural settlement. Results indicate that the impact of factor pertaining to rural population and environmental issues in greater than other proposed factors, and has undermined the impact of legislative and economic considerations on land allocation.

Planning of cities in order to respond to considerable needs of urban population, is one of the most important concerns of urban managers and authorities. Urban development plans which have been provided to respond to these issues, have different objectives and characteristics. Hence different plans are developed to plan and organize cities. Most of these plans are being prepared without consideration of outcomes and results of previous plans. They dont evaluate and measure the success of previous plans in improving the condition of city. Evaluation enhances planning practice. It legitimizes planning before citizens, providing sustained appraisals on planning products, procedures and results. Implementation evaluation of urban development plans can result in creating efficient and responding plans. Many regulatory-oriented planning systems employ comprehensive land-use plans as a central tool for carrying out planning policies. Aside from the vast effort invested in planning, land-use plans have a direct economic effect on land value and property rights. So, Land-use plan as a part of urban development plan which has considerable influence on public and private interest, needs to be evaluated more than other parts. Implementation evaluation of plans is performed based on three main approaches: Conformance-based, Performance-based and synthesis approaches. Conformance-based evaluation means judging the success or failure of planning using one or two criteria - the conformance degree between the outcomes on the ground and the plan proposals and the promotion of planning goals and objectives through the available implementation instruments-. Performance-based evaluation follows from defining a plan as a decision framework. After distinguishing between project plans and strategic plans and concluding that the conformance criterion is useful only in the evaluation of the former, performance-based approach develops the performance criterion to assess strategic plans. In some few studies on plan implementation, researchers explore the potentialities of an integrated use of both approaches and their simultaneous application for comparative purposes. These researchers have tried to create new methods based on the strengths of those approaches. This study wants to measure the conformance between proposed plan and current condition of city and to evaluate the implementation of land-use plan of Lavasan with regards to this. The evaluation is based on three factors: land-use, density and floor area ratio. Non- conformances in land-use has been grouped in 12 main groups. Results show that 54 percent of city area has non -conformance in land -use which 12 percent of these non -conformances are basic and they represent disobedience from proposed plan. Moreover, 7 percent of city area is allocated to lots with non-conformance in floor area ratio and 9 percent of city area is allocated to lots with non -conformance in density. 5 percent of lots have both non - conformances - floor area ratio and density-. Most of non- conformances has been occurred in central neighborhoods of city. In order to reduce these non-conformances, it is useful to consider specific situation of Lavasan in providing new plans. Control and supervision of plan implementation is also helpful for improving plan's degree of success.

One of the major studies in order to understand the distribution of activities in the city is studying how urban land use is organized. Rapid urban development in the last century and especially in recent decades, causing widespread plans for building a harmonious development in urban arias. Comprehensive plan for the city as an important tool in the management of inventory in the decades, since its emergence had faced with with faint. Today, the urban green space as one of the main indicators of sustainable development and healthy city is referred to be a measureable factor for urban development. Impact of urban development and the complexity of environmental problems, the availability of green space and expanding it to seem to be inevitable. One of the major problems for cities is urban green space that adversely affects every aspect of human life. Compared with urban planning standards, in addition to the low level of use of green space in cities and its variations has created some problems such as the lack of equitable distribution of green space in the city and pointed out the problems of citizens. From the perspective of planning and urban design, landscape spread wider context of the development of vegetation and improve the natural environment of the city. Standards per capita should be made clear, before any plans for the development of urban green space and, In line with the above, the present study aims to assess the user realizing urban development projects; emphasizing the use of green space in the city Dorud a descriptive - analytical study. Studies show researcher adopted comprehensive plan Dorud compared to existing designs residential, educational, cultural, recreational, medical, industrial, and transportation and is quoted. Other members of the proposed Master Plan, adopted in with unrealized designs are available. Dorud in use per capita green space in the status quo is 4.04 square meters, The 9 square meters per capita compared with the approved plan has been approved, is not realized. Model of SWOT strengths of 11 to 25 internal weaknesses and external opportunities for 11 to 16 external threats In conjunction with the existing implementations of Urban Development Goals have been identified and studied. Impacts of urban development and the complexity of environmental issues, and expand the availability of green space it always has been inevitable. Concentrated in cities as centers of human activity, in order to ensure its sustainability choice but to accept the structure and function of natural systems are affected... Among these green spaces as an integral and essential component of the body cities. They have a fundamental role in the metabolism deficiency can cause serious problems in urban life created Due to the critical nature of urban green space management mechanism and also the necessity of justice in an effort to expand access to city parks and green spaces suitable, Equitable distribution of land in the city, is considered one of the issues of urban planning, Therefore, to address the issue of social justice in the distribution and location of urban essential problem seems to be. Conducted studies on how to increase public participation in the creation, preservation and maintenance of green spaces (parks within the city) and increasing social control through the use of popular participation is essential Studies undertaken to prepare a comprehensive plan for the city's green spaces Dorud and integrated planning for this type of user, any plan to create green space, And urban parks in the city should be in the context of the proposed studies.

Landscape Architecture, as a newborn knowledge and profession, with the aim of enhancing & improving environmental qualities of urban-rural open spaces, is one of the main disciplines of environmental design. In Iran, unfortunately there has been wrong and superficial understanding about it. From the other viewpoint, practical domains and areas of this discipline have been increasing recently. Thus, giving a clear definition & theoretical fundamentals of landscape architecture in order to correct probable misunderstanding about it is the main goal of this research. This article intends to identify the correct understanding about landscape architecture, in the base of investigating definitions, historical background, values & approaches & practical domain of this profession. In the first step, the background of the landscape architecture analyses as a three part (disciplinary- artistic- professional). In the next step, the main definitions of this field explain and classify to five conceptual categories. Values and approaches of landscape architecture survey according to the recent theories. Finally, practical and professional domains of this field, which landscape architects work on them, identify.
